Nathan, Since a .exe self-extracting archive is just an archive with a simple extraction program prepended to it, it is possible to make one out of ANY type of archive. You could even make a self-extracting .tar.gz if you really wanted to. So the answer to when unzip will and won't work is this: Unzip will only work if the archive attached to the extractor is a .zip file. Obviously, this means the key to opening any self-extracting archive is figuring out which type of archive it is. I've found that most archives in the Windoze world (expecially installers) are usually either .zip or .cab archives. So if unzip won't do it for you, I'd suggest having a go with cabextract (/usr/ports/archivers/cabextract) and seeing where that gets you.
